Acute kidney failure in the perioperative of cardiovascular surgery

Introduction: Severe renal lesion after cardiac surgery remains as an important cause of postoperative morbidity and the occurrence of non-communicable chronic diseases in patients referred for this type of surgical procedure is higher. The incidence of the severe renal lesion depends on the type of surgery and on renal functions before the operation, but many are the factors contribution to the onset of such lesion. Objectives: To expand current knowledge about patients with acute kidney failure in relation to the main aspects of their incidence after cardiac surgery or not associated with extracorporeal circulation and its influence on anesthetic conduction and postoperative behavior in the appearance of the referred kidney damage. Methods: We consulted the bibliographic databases Pubmed, Hinari, Clinical Key, Lilacs, specialty textbooks and doctoral dissertations, from which more than 25 review articles, mostly updated, were taken Results: The decrease in morbidity and mortality depends on the knowledge about risk factors associated with the onset of acute kidney failure in the postoperative period of the cardiovascular surgical intervention, as well as the preparation of the conditions to confront the possible complications. Conclusions: The correct choice of anesthetic technique, as well as the monitoring of hematological and clinical parameters in the perioperative period improves recovery, less stay in the intensive care and cardiology units, considerable saving of resources and greater well-being for patients.
